Tantalum

Tantalum is a rare metal with the symbol Ta and atomic number 73.
It is typically found in the ore columbite-tantalite (coltan) and is a solid at room temperature.
Tantalum is a shiny, silvery metal that is soft when pure and has an extremely high melting point.
It is one of the hardest materials known when combined with graphite.
The Central Government’s notification of Tantalum as a Critical and Strategic Mineral highlights its importance in various industries.

Properties of Tantalum

Classified as a transition metal, Tantalum is virtually resistant to corrosion due to an oxide film on its surface.
It is ductile when pure, meaning it can be stretched or drawn into a thin wire without breaking.
Tantalum belongs to a class of metals known as refractory metals, which are defined by their strong resistance to heat and wear.

Tantalum is prominently used in the electronic sector, particularly in the production of capacitors.
Its high melting point makes it an ideal substitute for platinum in various applications.
Tantalum is also used in making components for chemical plants, nuclear power plants, aeroplanes, and missiles.
Its non-reactive properties make it suitable for use in surgical equipment and implants.
